Next step should be to check the fuse-resistors and low values resistors for open conditions as well the solder joints on them.
These parts are located near the STKICs.
Also if you can measure the voltage that power up the STK's. If you do not have the schematic diagram, check the ICs data sheet to know where the voltage is getting to the ICs.
You may have to do the convergence adjustment manually after you replaced those parts.
Good Luck.

No.Should cost u like $300-350 for parts and labors.Get it fixed any local tv shops can fixed this problems,very common problems for DLP CRTS tubs design projection tvs Tv have a problems known as a convergence problems,it is dead.The tv convergence board it is dead,that why ur tv picture colors lines R,G,B mis alignments,have pictures colors shadow or 3D pictures look alike.The tv convergence board must have it parts replace like 2 STK convergence ICS and some or all of it resistors to fixed the convergence board to solved convergence pictures problems.

Any colors mis alignments R,G,B.The tv have a problems known as convergence problems,it dead.The tv convergence board the 2 STK convergence ICS and some or all it resistors are dead.These parts,must be replaced in the tv convergence board to solved the convergence problems.The shop will cost u $300-350 for parts and labors.
